Correct option is D
Given:
There are four entries in column A that must be matched with entries in column B. Each correctly matched option scores one mark, while no marks are awarded for incorrect matches. We need to determine which of the following marks cannot be scored.
Solution:
Since there are four entries in column A and four entries in column B, we have the following possible outcomes:
If all four matches are correct, the score is 4.
If three matches are correct, the score is 3.
If two matches are correct, the score is 2.
If one match is correct, the score is 1.
If none are correct, the score is 0.
Each of these scores (0, 1, 2, 3, and 4) represents all possible scores that can be achieved based on correct or incorrect matches.
However, the question specifically asks which mark cannot be scored. Since we have covered all possible scores from 0 to 4, it appears all these scores can be achieved under different matching scenarios.
Thus, the answer is (d) 4 because all marks from 0 to 4 are possible scores, meaning there is no mark that cannot be scored.
